Help! What is it, and how do I get rid of it. Found three on my Brugmansia (I think that's what it's called)--completely stripped one whole branch/stem. I spray with Ortho. One of my tomato bushes looks the same way, but I couldn't spot this monster or anything on it. Of course, being green on green it would be very hard to see. I've used the liquid seven on the tomatoes. Is there something better? It has a big horn on the top of it's head. Does it sting. My son pulled them off with a pair on tongs, which they really seemed to fight. Ugh! Eeeeeuuuuweeee......
